Our take on the Definitive Technology Mythos Gem XL

by Kristen Schaub
Definitive Technology

Add this versatile speaker to your setup for rich, dynamic sound

Definitive Technology's Mythos Gem XL delivers surprisingly big sound in a compact package. This speaker houses two 4-1/2" mid/bass drivers that are angled away from each other to create a spacious, lifelike soundstage. They flank a 1" pure aluminum dome tweeter that reveals lots of detail and nuance without adding a trace of edginess.

Slim profile makes it easy to place in your room

The enclosure is made of black hand-polished aluminum for a sleek look that'll go well with most modern décors. A keyhole slot on the back of the speaker allows you to mount it on your wall for out-of-the-way placement. The Gem XL is voice-matched with the entire Mythos series, so they're perfect for use as compact surround speakers in a system made up of larger Mythos main speakers. Or use the Gem XL as your front and surround speakers, with the Mythos Seven center channel speaker and either the SuperCube 2000 or ProSub 800 subwoofer.

Did you know?
Your new speakers will probably sound better after several weeks of use than they do right out of the box. That's because the material surrounding the woofers will loosen up, allowing the drivers to move more fully. Definitive Technology estimates a break-in period of 24 to 48 hours of playback before the speakers will deliver optimum sound quality. For more information and helpful tips, check out this article from Definitive's website about conditioning your speakers.

Overview: The Definitive Technology Gem XL Satellite Loudspeaker provides big, high-definition sound as a front or back/side surround speaker. The Gem XL features two high-definition 4-1/2 inch high definition mid/bass drivers for life-like clarity and three-dimensional imaging and a 1-inch (25mm) pure aluminum dome tweeter for high frequency extension, detail and, smoothness. The Gem XL uses angled drivers to disperse the sound over a broader area. The satellite speaker features a hand-polished gloss aircraft-grade extruded aluminum enclosure with proprietary damping technologies to ensure total rigidity and accurate sound. The speaker can be placed on a table-top or wall-mounted.

Driver Technology

Angled Drivers: The Mythos Gem XL contains two 4-1/2 inch long-throw mid/bass drivers that are angled in opposite directions to broaden the midrange dispersion. The bass roll-off of the Mythos Gem XL is smooth and controlled, allowing it to seamlessly blend with a powered subwoofer, such as Definitive's SuperCubes, for audiophile-grade home theater performance.

Pure Aluminum Dome Tweeter: The Mythos Gem XL is equipped with a 1-inch ferrofluid-dampened pure aluminum dome tweeter for extended, smooth highs.

Linkwitz-Riley Crossover Network: The Mythos Gem XL uses a sophisticated Linkwitz-Riley Crossover Network to perfectly blend the drivers into a sonically seamless audio environment.

Voice Matched: The Mythos Gem XL is voice-matched with the complete Definitive Technology Mythos Series speaker line-up.

Break-In Period: The Mythos Gem XL will sound good right out of the box; however, an extended break-in period of 20-40 hours or more of playing is required to reach full performance capability. The break-in period allows the suspensions to work in and results in full bass, a more open midrange, and smoother high frequency reproduction.

Enclosure Design

Extruded Aluminum Enclosure: The Mythos Gem XL enclosure is hand-polished gloss back aircraft-grade extruded aluminum with proprietary damping technologies that ensure total rigidity. All components are mounted on a resonance-free PolyStone baffle. These construction technologies along with state-of-the-art drivers and tweeter serve to deliver high quality sound with a wide soundstage, pinpoint imaging, high dynamic impact, and superb realism.

Connections

Binding Posts: The Mythos Gem XL is equipped with a pair of gold-plated, 5-way binding posts to attach your receiver's speaker wire.

Mounting Options

Mounting: The Mythos Gem XL comes with a wall-mount bracket, so you can easily mount the speaker on the wall (mounting screws not included). The Mythos Gem XL also features a 1/4"-20 threaded insert for using Definitive Technology's optional articulating wall-bracket (ProMount 90) to mount the speaker on the wall. In addition, the Mythos Gem XL can be placed on a table-top, shelf, or stand.

Applications: The Mythos Gem XL is a versatile speaker which can be used as a front or rear/side surround speaker.

Absolutely amazing

Written By Kevin, Palo Alto, CA on Wednesday, September 18, 2013
Crutchfield Customer Review (What's this?)
 
I got these after five years of requests to downsize my Polk RTi A6s from the wife; they sounded amazing but were just too massive. I tried the Klipsch G-42 passive soundbar first but was dismayed at how pathetic it sounded compared to my beloved Polks. Sent it back to Crutchfield and called up to ask what they would recommend. Two different salespeople pointed me to Definitive Technologies and holy cow am I glad that they did.

These speakers are very small and pack the power of an artillery brigade; the diminutive size does nothing to impede the massive sound that they produce. They are clear with very little (no detectable) distortion, and have an impressively powerful midrange, considering they only have 4 1/2" drivers.

I have had a lot of awesome sound gear over the years and I have never been as impressed as I was when I fired the DefTech Mythos Gem XLs up for the first time.
